Hello, if someone could help me with the second part of this problem, I would be so grateful.(adsbygoogle = window.adsbygoogle || []).push({});

A rock is tossed straight up with a velocity of + 20 m/s When it returns, it falls into a hole 10 m deep.

What is the rock's velocity as it hits the bottom of the hole?

I got -24.4 m/s for this.

How long is the rock in the air, from the instant it is released until it hits the bottom of the hole?

This is what I have no idea how to figure out.

Any help you can give me would be much appreciated.
